 Each table will receive a gracious amount of skittles. [You may need to trade some colors with
classmates.] It does not matter what colors you use… Please do NOT argue about who gets what
colors. The skittles will represent the atom’s electrons

Helpful Hints:
Remember that the Atomic Number is the number of Protons in an atom.
The Mass Number is the number or Protons and Neutrons combined.
The number of Electrons equals the number of Protons in an atom.
